Featured pages images …

Hi,

Still happy with this theme. Thanks!

I have done some customization for the featured pages images. I have got them rectangle (270x150px).

This is what I have done, they are strechted. How can I fix it?

.home .round-div {
border-color:   transparent;
}
.thumb-wrapper img, .round.div {
    -webkit-border-radius: 10px;
    border-radius: 10px;
 }
.thumb-wrapper, .round.div  {
height: 150px;
}
#main-wrapper > div.container.marketing img {
height: 150px;
}
.fp-text-one, .fp-text-two, .fp-text-three {
   text-align: center;
   min-height:   90px;
}

Whatelse do I need to change?
